Sayyiduna Uqbah bin Amir (may Allah be pleased with him) narrates: the Prophet (peace and blessings be upon him) said: "The first two disputants on the Day of Resurrection will be two neighbours."
Ahmad recorded it, and al-Tabarani recorded something similar; one of al-Tabarani's two chains has narrators who are the narrators of the "Sahih", except Abu Ushshanah, and he is thiqah (trustworthy).
